FIELD OF THE INVENTION

The present invention provides novel aryl dihydropyridinone and piperidinone compounds, and their analogues thereof, which are MGAT2 inhibitors, compositions containing them, and methods of using them, for example, for the treatment or prophylaxis of diabetes, obesity, dyslipidemia and related conditions.

BACKGROUND OF THE INVENTION

The prevalence of obesity and diabetes is increasing at an alarming rate. According to WHO, in 2008, 70% of the U.S. adult population was overweight, and among them 33% were obese. Parallel to the explosive number of people becoming overweight and obese, in 2008, it was estimated that 12.3% of the U.S. population had elevated blood glucose [http://www.who.int/diabetes/facts/en/]. The obesity/diabetes epidemic is not unique to the U.S. According to WHO (Fact Sheet No. 312, September 2012), 347 million people worldwide have diabetes. Treating obesity and improving glycemic control effectively and safely remain major challenges for modern medicine.

Monoacylglycerol acyltransferase 2 (MGAT2) has emerged as an attractive target for the treatment of obesity and type II diabetes [Yen, C. L. et al., Nat. Med., 15(4):442-446 (2009)]. MGAT2 is highly and selectively expressed in the small intestine where it exerts a pivotal role in the monoacylglycerol-pathway for the absorption of dietary fat. When dietary fat is ingested, pancreatic lipase digests triglycerides into free fatty acids and 2-monoacylglycerol, which are absorbed by intestinal epithelial enterocytes. Once inside enterocytes, free fatty acids and 2-monoacylglycerol are used as building blocks to resynthesize triglycerides by two sequential acylation steps; first by MGAT and then by DGAT enzyme reactions. Triglycerides are then incorporated into chylomicrons and secreted into lymph to be utilized as an energy supply for the body. MGAT2 knockout mice exhibit a healthy metabolic phenotype and show resistance to high-fat diet induced obesity, improvement in insulin sensitivity and decreased fat accumulation in liver and adipose tissue. In addition, genetic deletion of MGAT2 produces mice with increased levels of GLP1 [Yen, C. L. et al., Nat. Med., 15(4):442-446 (2009)]. Taken together, these data show that MGAT2 inhibitors hold promise to treat metabolic disorders such as obesity, type II diabetes and dyslipidemia.

The term “counter ion” is used to represent a negatively charged species such as chloride, bromide, hydroxide, acetate, and sulfate or a positively charged species such as sodium (Na+), potassium (K+), ammonium (R_(n)NH_(m)+ where n=0-4 and m=0-4) and the like.

When a dotted ring is used within a ring structure, this indicates that the ring structure may be saturated, partially saturated or unsaturated.

As used herein, the term “amine protecting group” means any group known in the art of organic synthesis for the protection of amine groups which is stable to an ester reducing agent, a disubstituted hydrazine, R4-M and R7-M, a nucleophile, a hydrazine reducing agent, an activator, a strong base, a hindered amine base and a cyclizing agent. Such amine protecting groups fitting these criteria include those listed in Wuts, P. G. M. and Greene, T. W. Protecting Groups in Organic Synthesis, 4th Edition, Wiley (2007) and The Peptides: Analysis, Synthesis, Biology, Vol. 3, Academic Press, New York (1981), the disclosure of which is hereby incorporated by reference. Examples of amine protecting groups include, but are not limited to, the following: (1) acyl types such as formyl, trifluoroacetyl, phthalyl, and p-toluenesulfonyl; (2) aromatic carbamate types such as benzyloxycarbonyl (Cbz) and substituted benzyloxycarbonyls, 1-(p-biphenyl)-1-methylethoxycarbonyl, and 9-fluorenylmethyloxycarbonyl (Fmoc); (3) aliphatic carbamate types such as tert-butyloxycarbonyl (Boc), ethoxycarbonyl, diisopropylmethoxycarbonyl, and allyloxycarbonyl; (4) cyclic alkyl carbamate types such as cyclopentyloxycarbonyl and adamantyloxycarbonyl; (5) alkyl types such as triphenylmethyl and benzyl; (6) trialkylsilane such as trimethylsilane; (7) thiol containing types such as phenylthiocarbonyl and dithiasuccinoyl; and (8) alkyl types such as triphenylmethyl, methyl, and benzyl; and substituted alkyl types such as 2,2,2-trichloroethyl, 2-phenylethyl, and t-butyl; and trialkylsilane types such as trimethylsilane.

As referred to herein, the term “substituted” means that at least one hydrogen atom is replaced with a non-hydrogen group, provided that normal valencies are maintained and that the substitution results in a stable compound. Ring double bonds, as used herein, are double bonds that are formed between two adjacent ring atoms (e.g., C═C, C═N, or N═N).

In cases wherein there are nitrogen atoms (e.g., amines) on compounds of the present invention, these may be converted to N-oxides by treatment with an oxidizing agent (e.g., mCPBA and/or hydrogen peroxides) to afford other compounds of this invention. Thus, shown and claimed nitrogen atoms are considered to cover both the shown nitrogen and its N-oxide (N→O) derivative.

When any variable occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with 0-3 R, then said group may optionally be substituted with up to three R groups, and at each occurrence R is selected independently from the definition of R.

When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any atom on the ring. When a substituent is listed without indicating the atom in which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded via any atom in such substituent.

Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.

The phrase “pharmaceutically acceptable” is employed herein to refer to those compounds, materials, compositions, and/or dosage forms that are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, and/or other problem or complication, commensurate with a reasonable benefit/risk ratio.

As used herein, “pharmaceutically acceptable salts” refer to derivatives of the disclosed compounds wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic groups such as amines; and alkali or organic salts of acidic groups such as carboxylic acids. The pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. For example, such conventional non-toxic salts include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, and nitric; and the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutamic, benzoic, salicylic, sulfanilic, 2-acetoxybenzoic, fumaric, toluenesulfonic, methanesulfonic, ethane disulfonic, oxalic, and isethionic, and the like.

The pharmaceutically acceptable salts of the present invention can be synthesized from the parent compound that contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, nonaqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are preferred. Lists of suitable salts are found in Remington: The Science and Practice of Pharmacy, 22^(nd) Edition, Allen, L. V. Jr., Ed.; Pharmaceutical Press, London, UK (2012), the disclosure of which is hereby incorporated by reference.

In addition, compounds of formula I may have prodrug forms. Any compound that will be converted in vivo to provide the bioactive agent (i.e., a compound of formula I) is a prodrug within the scope and spirit of the invention. Various forms of prodrugs are well known in the art. For examples of such prodrug derivatives, see:

Compounds containing a carboxy group can form physiologically hydrolyzable esters that serve as prodrugs by being hydrolyzed in the body to yield formula I compounds per se. Such prodrugs are preferably administered orally since hydrolysis in many instances occurs principally under the influence of the digestive enzymes. Parenteral administration may be used where the ester per se is active, or in those instances where hydrolysis occurs in the blood. Examples of physiologically hydrolyzable esters of compounds of formula I include C₁₋₆alkyl, C₁₋₆alkylbenzyl, 4-methoxybenzyl, indanyl, phthalyl, methoxymethyl, C₁₋₆ alkanoyloxy-C₁₋₆alkyl (e.g., acetoxymethyl, pivaloyloxymethyl or propionyloxymethyl), C₁₋₆alkoxycarbonyloxy-C₁₋₆alkyl (e.g., methoxycarbonyl-oxymethyl or ethoxycarbonyloxymethyl, glycyloxymethyl, phenylglycyloxymethyl, (5-methyl-2-oxo-1,3-dioxolen-4-yl)-methyl), and other well known physiologically hydrolyzable esters used, for example, in the penicillin and cephalosporin arts. Such esters may be prepared by conventional techniques known in the art.

Preparation of prodrugs is well known in the art and described in, for example, King, F. D., ed., Medicinal Chemistry: Principles and Practice, The Royal Society of Chemistry, Cambridge, UK (2nd edition, reproduced, 2006); Testa, B. et al., Hydrolysis in Drug and Prodrug Metabolism.

Isotopically-labeled compounds of the invention can generally be prepared by conventional techniques known to those skilled in the art or by processes analogous to those described herein, using an appropriate isotopically-labeled reagent in place of the non-labeled reagent otherwise employed.

The term “solvate” means a physical association of a compound of this invention with one or more solvent molecules, whether organic or inorganic. This physical association includes hydrogen bonding. In certain instances the solvate will be capable of isolation, for example when one or more solvent molecules are incorporated in the crystal lattice of the crystalline solid. The solvent molecules in the solvate may be present in a regular arrangement and/or a non-ordered arrangement. The solvate may comprise either a stoichiometric or nonstoichiometric amount of the solvent molecules. “Solvate” encompasses both solution-phase and isolable solvates.

Preferred methods include, but are not limited to, those described below. The reactions are performed in a solvent or solvent mixture appropriate to the reagents and materials employed and suitable for the transformations being effected. It will be understood by those skilled in the art of organic synthesis that the functionality present on the molecule should be consistent with the transformations proposed. This will sometimes require a judgment to modify the order of the synthetic steps or to select one particular process scheme over another in order to obtain a desired compound of the invention.

The novel compounds of this invention may be prepared using the reactions and techniques described in this section. Also, in the description of the synthetic methods described below, it is to be understood that all proposed reaction conditions, including choice of solvent, reaction atmosphere, reaction temperature, duration of the experiment and workup procedures, are chosen to be the conditions standard for that reaction, which should be readily recognized by one skilled in the art. Restrictions to the substituents that are compatible with the reaction conditions will be readily apparent to one skilled in the art and alternate methods must then be used.

Synthesis

The compounds of Formula (I) may be prepared by the exemplary processes described in the following schemes and working examples, as well as relevant published literature procedures that are used by one skilled in the art. Exemplary reagents and procedures for these reactions appear hereinafter and in the working examples. Protection and de-protection in the processes below may be carried out by procedures generally known in the art (see, for example, Wuts, P. G. M. and Greene, T. W. Protecting Groups in Organic Synthesis, 4th Edition, Wiley (2007)). General methods of organic synthesis and functional group transformations are found in: Trost, B. M. and Fleming, I., eds., Comprehensive Organic Synthesis: Selectivity, Strategy & Efficiency in Modern Organic Chemistry, Pergamon Press, New York, N.Y. (1991); Smith, M. B. and March, J., March's Advanced Organic Chemistry: Reactions, Mechanisms, and Structure. 6th Edition, Wiley & Sons, New York, N.Y. (2007); Katritzky, A. R. and Taylor, R. J. K., eds., Comprehensive Organic Functional Groups Transformations II, 2nd Edition, Elsevier Science Inc., Tarrytown, N.Y. (2004); Larock, R. C., Comprehensive Organic Transformations, VCH Publishers, Inc., New York, N.Y. (1999), and references therein.

For example, compounds of Formula (II), where R³═R⁴═H and R⁶═CN, can be made according to Scheme 1. Ketones 1 and 2 and 2-cyanoethyl acetate (3) are heated to between 80° C. and 110° C. with ammonium acetate in a solvent such as DMF or DMSO. Ketones 1 and 2 may be different or the same.

Alternatively, compounds of Formula (II), where R³═R⁴═H, may be made according to Scheme 2. α-Bromoketone 4 is combined with triphenylphosphine in a solvent such as THF, CH₂Cl₂ or 1,4-dioxane at temperatures between room temperature and reflux. The intermediate triphenylphosphonium bromide is treated with base, such as NaOH, in a solvent such as methanol and water to form the phosphorous ylide 5. The phosphorous ylide 5 is heated to 80° C. with ketone 2 in a suitable solvent such as THF or DMSO to give α,β-unsat'd ketone 6, which may exist as a mixture of E/Z isomers. Microwave irradiation may be employed to shorten the reaction time. α,β-Unsat'd ketone 6 is treated with concentrated aq NH₄OH in a solvent such as DMSO in a sealed vessel to provide amine 7. Alternatively, alkene 6 may be treated with NH₃ in a solvent such as DMSO or DMSO and methanol in a sealed vessel to provide amine 7. Amine 7 is couple with carboxylic acid 8 using a variety of amide bond forming reactions. For example, carboxylic acid 8 may be converted to the corresponding acid chloride using oxalyl chloride in a solvent such as CH₂Cl₂ and catalytic DMF. Alternatively, when R⁶ is an amide or a heterocycle, the carboxylic acid 8 may be activated using triphenylphosphine and trichloroacetonitrile in a suitable solvent such as CH₂Cl₂. The acid chlorides thus formed are combined with amine 7 in a suitable solvent such as CH₂Cl₂ or CH₂Cl₂ and DMF in the presence of a base, preferably pyridine. When R² is CF₃, cyclization of amide 9 to a compound of Formula (I) typically occurs during the work-up procedure for amide 9; for example, when an EtOAc solution of amide 9 is washed with sat'd aq NaHCO₃. When cyclization does not occur under these conditions, cyclization may be affected by stirring amide 9 in the presence of a weak base such as piperidine in a suitable solvent such as EtOH at a temperature between room temperature and reflux.

An alternate synthesis to α,β-unsaturated ketone 6, where R¹ is —(CH₂)_(m)-(phenyl substituted with 0-3 R^(b)) and m=0, is shown in Scheme 3. Aryl bromide 10 and α,β-unsat'd ester 11 are coupled using palladium (II) acetate, tetrabutylammonium chloride and dicyclohexylamine in DMA at 110° C. α,β-Unsat'd ester 12 is combined with O,N-dimethylhydroxyl-amine 13 in the presence of a strong base such as iso-propylmagnesium bromide in an aprotic solvent such as THF. α,β-Unsat'd amide 14 is combined with aryl magnesium halide 15 to provide α,β-unsat'd ketone 6. The identity of the halide in the aryl magnesium halide is dependent upon availability of the aryl halide used to make the Grignard reagent; typically the halide is chloride or bromide.

Non-commercial α,α□,α-trifluoroketones 2, where R²═CF₃, may be made from the corresponding aldehyde 16 as shown in Scheme 4. Aldehyde 16 is reacted with trimethyl-(trifluoromethyl)silane in the presence of a fluoride source, for example cesium fluoride, using a suitable solvent such dimethoxyethane at room temperature. Other fluoride sources, such as potassium hydrogen fluoride or tetrabutylammonium difluorotriphenylsilicate, and other solvents, such as THF or acetonitrile and methanol, may also be employed. Trifluoromethyl alcohol 17 is oxidized using, for example, Dess-Martin periodinane in a suitable solvent such as CH₂Cl₂.

Ketones of formula 2 may be made according to Scheme 5. For example, aryl halide 18, where X=bromine and the aryl group is a suitable chemical moiety to form a Grignard reagent, is combined with magnesium metal in the presence of an initiator such as iodine in a suitable solvent such as THF. Other alkyl halides having a chemical moiety suitable for formation of Grignard reagents, other halides such as chlorine or iodine, other solvents such as diethyl ether or 1,4-dioxane, and other initiators such as 1,2-dibromoethene, may be employed as determined by one skilled in the art. Grignard reagent 19 is combined with amide 20 in a suitable solvent such as THF to provide ketone 2. Other solvents such as 1,4-dioxane or diethyl ether may be employed as determined by one skilled in the art.

Compounds of Formula 23 having R³═R⁴═H, R¹═(CH₂)_(m)-(phenyl substituted with 0-3 R^(b)) where m=0, and at least one R^(b)═(CH₂)_(n)—(X)_(t)—(CH₂)_(m)—R^(c) where n=m=t=0, or n=m=0 and t=1 when X═O or NH, and R^(c) is a suitable chemical moiety to participate in palladium cross coupling reactions, may be made according to Scheme 6. Compound 21 is heated with boronic acid 22, where R═H, in the presence of a palladium catalyst and base using a suitable solvent such as 1,4-dioxane, toluene, DMF with or without water. Boronic acid 22 may be substituted with alternative boronic acid analogs such as boronate esters, trifluoroborates, and others known to those skilled in the art. Palladium catalyst commonly employed include, but are not restricted to, Pd(PPh₃)₄ and PdCl₂(dppf). Other palladium catalyst known to those skilled in the art may be employed. Bases commonly employed include, but are not restricted to, K₃PO₄ and K₂CO₃. Other bases known to those skilled in the art may also be employed. When n=m=0 and t=1 when X═O or NH, biarylethers or biarylamines such as 23 can be obtained from 21 when G=OH. Alternatively, biaryl ethers and amines can also be obtained from 21, when G=boronic acid or equivalent, via metal-catalyzed coupling with suitable phenols or amines.

Compounds of Formula 27 having R³═R⁴═H, R¹═—(CH₂)_(m)-(phenyl substituted with 0-3 R^(b)) where m=0, and at least one R^(b)═—-(CH₂)_(n)—(X)_(t)—(CH₂)_(m)—R^(c) where n=0, t=1, m=1-4 and X ═O, may be made according to Scheme 7. Bromide 24 is treated with tris(dibenzylideneacetone)palladium (0) in the presence of bis(1,1-dimethylethyl)[2′,4′,6′-tris(1-methylethyl)[1,1′-biphenyl]-2-yl]-phosphine (t-butyl-Xphos) using 1,4-dioxane and water as solvent and KOH as base. Phenol 25 and alcohol 26 were stirred in the presence of triphenylphosphine and DIAD in a suitable solvent such as CH₂Cl₂.

Carboxylic acid 8, where R⁶═CONHR^(c), may be made according to Scheme 8. The mono-ester of malonic acid 28, where PG=benzyl group, and amine 29 are coupled together using standard amide bond forming conditions. For example, treatment of carboxylic acid 28 with oxalyl chloride in CH₂Cl₂ and DMF provides the acid chloride. The acid chloride is then combined with amine 29 in the presence of pyridine in a suitable solvent such as CH₂Cl₂. Other amide bond forming reaction known to those skilled in the art may be employed. The benzyl group is removed using a combination of hydrogen gas and 10% palladium on carbon in a suitable solvent such as methanol or methanol and EtOAc. Other PG moieties and methods for their removal known to those skilled in the art may be employed.

Compounds of Formula (I), where R³ and R⁴ are combined with the carbon atom to which they are attached to form a 3-6 membered carbocycle, or R³═R⁴═F, may be made according to Scheme 9. For example, to synthesize compounds for Formula (I) where R³ and R⁴ are combined with the carbon atom to which they are attached to form a 3-membered ring (i.e., cyclopropyl), β-ketoester 30 is stirred at room temperature with 1,2-dibromoethane in the presence of a base, for example K₂CO₃, in a suitable solvent such as DMF to provide the cyclopropyl β-ketoester 31. Cyclopropyl β-ketoester 31 is stirred with a suitable amine, such as benzyl amine, in the presence of a suitable Lewis acid, such as TiCl₄, in a solvent such as CH₂Cl₂ starting at 0° C. then warming to room temperature. Other amines, Lewis acids, solvents and temperatures may be used as determined by those skilled in the art. The use of benzylamine provides imine 32, where PG=benzyl. Imine 32 is alkylated with, for example, trimethyl(trifluoromethyl)silane in the presence of a fluoride source such as potassium hydrogen fluoride and TFA, using acetonitrile and DMF. Other fluoride sources, such as tetrabutylammonium difluorotriphenylsilicate or cesium fluoride, other acids such as HOAc or HCl, and other solvents may be employed as determined by those skilled in the art. Use of trimethyl(trifluoromethyl)silane provides amino ester 33, where R²═CF₃. Ester hydrolysis of amino ester 33 was done in the presence of lithium iodide in refluxing pyridine to provide amino acid 34. Use of other hydrolysis conditions known to those skilled in the art may be employed. Cyclization of amino acid 34 to β-lactam 35 was affected by activating the carboxylic acid of amino acid 34 with oxalyl chloride in a suitable solvent such as CH₂Cl₂ containing catalytic DMF. The cyclization occurred spontaneously at room temperature to provide β-lactam 35. Other methods for activating the carboxylic acid may be employed as determined by those skilled in the art. β-Lactam 35 is arylated using an organometallic reagent. Organometallic reagents may include, for example, Grignard reagents or organolithium reagents, formed from a suitably substituted phenyl ring containing a halide atom able to react with either elemental magnesium to form a Grignard reagent or with an alkyl lithium reagent to form an phenyl lithium reagent via transmetallation. Exact conditions required to form these phenyl organometallic species must determined by those skilled in the art. A suitable aprotic solvent is used, for example, THF. Other suitable solvents may be employed as determined by those skilled in the art. The reaction is carried out between room temperature and reflux depending upon the identity of the organometallic reagent employed and the substitution pattern on β-lactam 35. The β-amino ketone 37 thus formed is deprotected using hydrogen gas and 10% palladium on carbon in a suitable solvent such as methanol containing 4.4% formic acid to provide β-amino ketone 38. Other conditions to remove the benzyl group may be employed as determined by those skilled in the art. β-Amino ketone 38 is acylated with carboxylic acid 8 using conditions described in Scheme 2 to give the β-keto amide 39. Stirring β-keto amide 39 with a base such as sodium ethoxide in a suitable solvent such as ethanol at room temperature provides compounds having Formula (I).

Compounds of Formula (I), where y is a single bond and R⁵═F may be made according to Scheme 10. This synthesis is exemplified for a compound of Formula (I) where R⁶═CN. Thus, a compound of Formula (I), where x is a single bond and R⁶═CN, was heated to 80° C. in the presence of a fluorinating reagent, 1-fluoro-4-hydroxy-1,4-diazoniabicyclo[2,2,2]octane bis(tetrafluoroborate), in a suitable solvent such as DMF in the presence of a base such as Na₂CO₃ to provide compounds of Formula (I), where y is a single bond, R⁵═F and R⁶═CN. Other fluorinating reagents, solvents and bases may be employed as determined by one skilled in the art.

Compounds of Formula (I), where x and y are both single bonds and R⁵═H, can be made according to Scheme 11. Reduction of compounds of Formula (I), where x equals a single bond and y equals a double bond, is carried out using a suitable catalyst such as palladium on carbon under an atmosphere of hydrogen gas at suitable pressure, such as 50 psi, to effect reduction of the double bond y to a single bond. Suitable solvents include, but are not restricted to, methanol.

Compounds of Formula (II), single enantiomer, where R³═R⁴═H, can be made according to Scheme 12. Ketone 2 was stirred with 2-methylpropane-2-sulfinamide in the presence of a suitable Lewis acid, such as Ti(OEt)₄, in a solvent such as THF at refluxed tempereature provides imine 40. Other Lewis acids, solvents and temperatures may be used as determined by those skilled in the art. Imine 40 is alkylated with ketone 1 in the presence of a base, such as LiHMDS, KHMDS, NaHMDS, or LDA in an aprotic solvent such as THF or ether at a temperature ranging from −78° C. to ambient to provide β-amino ketone 41 as a mixture of two diastereomers, which can be separated by silica gel chromatography to give the desired isomer 42. Other metal enolates (such as titanium enolate), solvents, and temperatures may be used as determined by those skilled in the art (T. P. Tang, J. A Ellman, J. Org. Chem. 1999, 64, 12-13, J. Org. Chem. 2002, 67, 7819-7832). Preferably, chiral S- or R-2-methylpropane-2-sulfinamide can be optionally used to generate each of the optically pure enantiomers of imine 40 that can allow for chiral induction to prepare diastereomerically enriched ketone 42. In these cases, the product mixture can be further purified by silica gel chromatography to obtain desired products with diaseteromeric excess of >97%. β-amino ketone 42 thus formed is deprotected using HCl in a suitable solvent such as MeOH to provide β-amino ketone 43. Other conditions to remove the t-butylsulfinyl group may be employed as determined by those skilled in the art. β-Amino ketone 43 is acylated with carboxylic acid 8 using conditions described in Scheme 2 to give the β-keto amide 44. Stirring β-keto amide 44 with a base such as sodium ethoxide in a suitable solvent such as ethanol at room temperature provides compounds having Formula (II).

Alternatively, compounds of Formula (II), where R³═R⁴═H, may be made according to Scheme 13. Ketone 2 can be reacted with 2-methylpropane-2-sulfinamide in the presence of a suitable Lewis acid, such as Ti(OEt)₄, in a solvent such as THF at a temperature ranging from ambient to reflux to provide imine 45. Other Lewis acids, solvents and temperatures may be used as determined by those skilled in the art. Imine 45 is alkylated with the enolate of an ester in a suitable aprotic solvent such as THF or ether starting at −78° C. then warming to 0° C. or room temperature to provide protected β-amino ketone 46 as a mixture of two diastereomers, which can be separated by silica gel chromatography to give each individual chiral compound. The generation of the ester enolate is achieved by treating the ester, such as methyl acetate, with a suitable base such as LHMDS, KHMDS, NaHMDS, or LDA in an aprotic solvent such as THF or ether at a temperature ranging from −78° C. to ambient. Other metal enolates (such as titanium enolate), solvents, and temperatures may be used as determined by those skilled in the art (T. P. Tang, J. A Ellman, J. Org. Chem. 1999, 64, 12-13, J. Org. Chem. 2002, 67, 7819-7832). Preferably, chiral S- or R-2-methylpropane-2-sulfinamide can be optionally used to generate each of the optically pure enantiomers of imine 45 that can allow for chiral induction to prepare diastereomerically enriched ester 46. In these cases, the product mixture can be further purified by silica gel chromatography to obtain desired products with diaseteromeric excess of >97%. The tert-butyl sulfinyl group of 46 is removed using acids such as HCl and TFA in a suitable solvent such as MeOH or dioxane to generate amino ester 47. Other conditions to remove the t-butylsulfinyl group may be employed as determined by those skilled in the art. β-Amino ketone 47 is acylated with carboxylic acid 8 using conditions described in Scheme 2 to give the β-keto amide 48. Stirring β-keto amide 48 with a base such as sodium ethoxide in a suitable solvent such as ethanol at room temperature to 80° C. provides cyclic enol 49. Other conditions can also by used to effect the cyclization as determined by those skilled in the art. Compound 49, when treated with stoichiometric amount of a chlorinating agent, such as POCl₃, at elevated temperature in an inert solvent such as toluene, is converted to mono-chloride 50. Chloride 50 can then react with various boronic reagents through a Suzuki-type of cross coupling reaction to generate compounds of Formula (II). The choices of boronic reagents, catalysts, ligands, bases, solvents and temperatures are well documented in the literature and can be selected appropriately by those skilled in the art.

Compounds of Formula (II), where R³═R⁴═H and R¹═CONHC₄₋₁₈ alkyl or CONH(CH₂)₁₋₈Ph can be made according to Scheme 14. The phosphorous ylide 5 is heated, using microwave irradiation, to 150° C. with α-ketoester 52 in a suitable solvent such as THF or DMSO to give α,β-unsat'd ketone 53. α,β-Unsat'd ketone 53 is treated with concentrated aq NH₄OH in a solvent such as DMSO in a sealed vessel to provide amine 54. Alternatively, alkene 53 may be treated with NH₃ in a solvent such as DMSO or DMSO and methanol in a sealed vessel to provide amine 54. Amine 54 is couple with carboxylic acid 8 using a variety of amide bond forming reactions. For example, carboxylic acid 8 may be converted to the corresponding acid chloride using oxalyl chloride in a solvent such as CH₂Cl₂ and catalytic DMF. Alternatively, the carboxylic acid 8 may be activated using 1-chloro-N,N,2-trimethylprop-en-1-amine in a suitable solvent such as CH₂Cl₂. The acid chlorides thus formed are combined with amine 54 in a suitable solvent such as CH₂Cl₂ or CH₂Cl₂ and DMF in the presence of a base, preferably pyridine. Other amide bond forming reaction known to those skilled in the art may be employed. Cyclization of amide 55 and subsequent hydrolysis to a the carboxylic acid 56 typically occurs by stirring amide 55 in the presence of a weak base such as piperidine in a suitable solvent such as EtOH at a temperature between room temperature and reflux or a base such as litium hydroxide in a suitable solvent such as THF and water at room temperature. Alternatively, when R⁶ is a nitrile, cyclization of amide 55 typically occurs by stirring amide 55 in the presence of a base such as lithium hydroxide in a suitable solvent such as THF and water at room temperature. Hydrolysis is then carried out under acidic conditions using a strong acid such as HCl in a suitable solvent such as acetic acid at temperatures between room temperature and 50° C. Carboxylic acid 56 and an amine are coupled together using standard amide bond forming conditions. For example, treatment of carboxylic acid 56 and an amine with HOBt, EDC and DIEA in the presence of pyridine in a suitable solvent such as DCM at room temperature provides compounds having Formula (II). Other amide bond forming reaction known to those skilled in the art may be employed.

Compounds of formula 60 having R^(e)=alkyl and R⁶=cyano can be synthesized by coupling acid 56 with N,O-dimethylhydroxylamine using typical amide bond forming reactions. For example, carboxylic acid 56 is coupled to N,O-dimethylhydroxylamine using EDC in the presence of base, preferably N-methylmopholine, in a suitable solvent, such as CH₂Cl₂, to provide the Weinreb amide 57. Other amide forming reactions known to those skilled in the art may also be employed. The intermediate Weinreb amide 57 is reacted with ethynylmagnesium bromide in an aprotic solvent such as THF at 0-35° C. to provide the acylacetylide intermediate 58. Compounds of formula 60 are obtained when acylacetylide intermediate 58 is reacted with hydrazine 59 in the presence of a base such as TEA in a suitable solvent such as EtOH.

Compounds of formula 63 having R^(b)=alkyl and R⁶=cyano can be synthesized by first coupling acid 56 with β-ketoamine 61 using typical amide bond forming reactions. For example, carboxylic acid 56 is coupled to α-ketoamine 61 using EDC and HOBt in the presence of base, preferably DIEA, in a suitable solvent, such as CH₂Cl₂, to provide β-ketoamide 62. Other amide forming reactions known to those skilled in the art may also be employed. 5-Alkyl substituted oxazole 63 is then obtained via the dehydrative cyclization of β-ketoamide 62 using a dehydrating agent, preferably POCl₃, in the presence of a suitable base, such as DIEA, in a suitable solvent such as dichloroethane at a temperature of 80-120° C.

IV. BIOLOGY

In mammals, there are two triglyceride synthesis pathways: glycerol-3-phosphate pathway and monoacylglycerol pathway. The former is mainly responsible for energy storage in the peripheral tissues such as fat, liver, skeletal muscle; the latter is essential for the dietary fat absorption which takes place in the small intestine. When dietary fat is ingested, pancreatic lipase digests triglycerides into free fatty acids and 2-monoacylglycerol, which are absorbed by intestinal epithelial enterocytes. Once inside enterocytes, free fatty acids and 2-monoacylglycerol are used as building blocks to resynthesize triglycerides by two sequential acylation steps; first by MGAT and then by DGAT enzyme reactions. Triglycerides are then incorporated into chylomicrons and secreted into lymph to be utilized as an energy supply for the body.

Monoacylglycerol acyltransferase 2 (MGAT2) is a membrane bound acyltransferase that belongs to diacylglycerol acyltransferase 2 (DGAT2) gene family. It is highly and selectively expressed in the small intestine. Genetic deletion of MGAT2 in mice decreased the rate of absorption for the orally ingested triglycerides, indicating that MGAT2 plays an important role for the intestinal MGAT/DGAT pathway [Yen, C. L. et al, Nat. Med., 15(4):442-446 (2009); Okawa, M. et al., Biochem. Biophys. Res. Commun., 390(3):377-381 (2009)]. When chronically challenged with a high fat diet, in contrast to wild type mice that became obese, MGAT2 knockout mice resisted the impact of high-fat feeding and demonstrated with a lower body weight, less adiposity, and less hepatic fat accumulation. In contrast to hyperinsulinemic wild type mice after high-fat challenge, MGAT2 deletion normalizes the insulin level and decreased fasting glucose. In the glucose tolerance test, they also had an improved glucose excursion. Consistent with their improved glycemic profile, MGAT2 knockout mice also had an increased level of GLP1, an incretin gut hormone that profoundly impacts glucose metabolism [Yen, C. L. et al., Nat. Med., 15(4):442-446 (2009)]. Taken together, it is expected that inhibition of MGAT2 through pharmacological intervention would provide the same benefit as demonstrated in the knock-out mice, e.g., resistance to weight gain, or conversely, reduction in fat body mass. In addition, MGAT2 inhibition would lead to an improved insulin sensitivity and glucose metabolism which either leads to a decrease in the incidence of Type II diabetes, or a treatment of diabetic condition.

It is also desirable and preferable to find compounds with advantageous and improved characteristics compared with known anti-diabetic agents, in one or more of the following categories that are given as examples, and are not intended to be limiting: (a) pharmacokinetic properties, including oral bioavailability, half life, and clearance; (b) pharmaceutical properties; (c) dosage requirements; (d) factors that decrease blood drug concentration peak-to-trough characteristics; (e) factors that increase the concentration of active drug at the receptor; (0 factors that decrease the liability for clinical drug-drug interactions; (g) factors that decrease the potential for adverse side-effects, including selectivity versus other biological targets; and (h) improved therapeutic index with less propensity for hypoglycemia.

As used herein, the term “patient” encompasses all mammalian species.

As used herein, the term “subject” refers to any human or non-human organism that could potentially benefit from treatment with a MGAT2 inhibitor. Exemplary subjects include human beings of any age with risk factors for metabolic disease. Common risk factors include, but are not limited to, age, sex, weight, family history, or signs of insulin resistance such as acanthosis nigricans, hypertension, dyslipidemia, or polycystic ovary syndrome (PCOS).

As used herein, “treating” or “treatment” cover the treatment of a disease-state in a mammal, particularly in a human, and include: (a) inhibiting the disease-state, i.e., arresting it development; and/or (b) relieving the disease-state, i.e., causing regression of the disease state.

As used herein, “prophylaxis” or “prevention” cover the preventive treatment of a subclinical disease-state in a mammal, particularly in a human, aimed at reducing the probability of the occurrence of a clinical disease-state. Patients are selected for preventative therapy based on factors that are known to increase risk of suffering a clinical disease state compared to the general population. “Prophylaxis” therapies can be divided into (a) primary prevention and (b) secondary prevention. Primary prevention is defined as treatment in a subject that has not yet presented with a clinical disease state, whereas secondary prevention is defined as preventing a second occurrence of the same or similar clinical disease state.

As used herein, “risk reduction” covers therapies that lower the incidence of development of a clinical disease state. As such, primary and secondary prevention therapies are examples of risk reduction.

“Therapeutically effective amount” is intended to include an amount of a compound of the present invention that is effective when administered alone or in combination to inhibit MGAT2 and/or to prevent or treat the disorders listed herein. When applied to a combination, the term refers to combined amounts of the active ingredients that result in the preventive or therapeutic effect, whether administered in combination, serially, or simultaneously.

A. Assay Methods MGAT SPA Assay

MGAT2 enzyme was assayed using membranes isolated from Sf9 cells expressing the recombinant human MGAT2 cDNA with 2-monooleoylglycerol and [³H]-oleoyl-CoA as substrates as described by Seethala et al. [Anal. Biochem., 383(2):144-150 (Dec. 15, 2008)]. Briefly, the assays were conducted in 384-well plates in a total volume of 30 μL at 25° C. In each assay, 200 ng of recombinant human MGAT2 membrane was incubated with 10 μM of 2-monooleoylglycerol and 15 μM of [³H]-oleoyl-CoA in 100 mM potassium phosphate (pH 7.4) for 20 min with various concentrations of compounds delivered in DMSO. The assay was terminated by the addition of 20 μl of Stopping Solution (7.5 mg/ml Yittrium Oxide Polylysine beads, 3.3 mg/ml Fraction V BSA and 200 μM Mercuric chloride in 50 mM HEPES, pH 7.4). The signal was measured 1 h after quenching the reaction using LEADSEEKER^(SM) for 5 minutes. To calculate the degree of inhibition, the zero level of enzyme activity (blank) was defined by the above assay procedure using membrane form Sf9 cell uninfected with baculovirus (Naive) and the 100% level of MGAT2 enzyme activity was defined by human MGAT2 assay with the vehicle DMSO. The IC₅₀s of inhibitors were determined by logistic 4 parameter equation in XL-fit.

MGAT LCMS Assay

The MGAT enzyme reactions were performed in CORNING® Falcon 96-well Polypropylene plates, in a total volume of 60 μL of 50 mM Potassium Phosphate buffer pH 7.4, containing a final concentration of 100 μM 2-oleoylglycerol, 15 μM oleoyl-Coenzyme A and 0.0013 μg/μL Human or Mouse MGAT-2 or 0.0026 μg/μL Rat recombinant MGAT-2 membranes expressed in Sf9 cells. Assay plates were run through a fully automated robotics system and shaken for 5 seconds every minute for a total 10 minutes. The reactions were then quenched with 120 μL of ice cold methanol containing 1 μg/mL 1,2-distearoyl-rac-glycerol as the internal standard. Plates were shaken for 2 minutes and spun down to remove protein precipitation. After the spin, samples were transferred to LC/MS compatible PCR plates. For LC/MS analysis, a ThermoFisher Surveyor pump, utilizing a Waters Symmetry C8, 50×2.1 mm column, was used for the chromatography of enzyme products. The buffer system consists of 0.1% formic acid in water with a mobile phase consisting 0.1% formic acid in methanol. The shallow gradient is 90-100% mobile phase in 0.2 min with a total run time of 2.3 min. The first 0.5 minutes of each injection was diverted to waste to eliminate the presence of Phosphate buffer in the enzymatic reaction. The column was run at 0.6 mL/min and a temperature of 65° C. Mass spectrometry analysis of the samples was performed on a ThermoFisher Quantum Triple quad utilizing APCI (+) as the mode of ionization. Data was acquired in Single Ion Monitoring (SIM) mode analyzing Diolein=m/z 603.6 (PRODUCT) and 1,2-distearoyl-rac-glycerol (IS)=m/z 607.6. The ratio of Diolein to internal standard (Peak Area Ratio) is utilized to calculate IC₅₀ values.

The exemplified Examples disclosed below were tested in the MGAT2 in vitro assays described above and were found having MGAT2 inhibitory activity. Table 1 below lists human MGAT2 IC₅₀ values measured for the following examples. “NT” denotes “Not tested”.

The compounds of this invention can be administered for any of the uses described herein by any suitable means, for example, orally, such as tablets, capsules (each of which includes sustained release or timed release formulations), pills, powders, granules, elixirs, tinctures, suspensions (including nanosuspensions, microsuspensions, spray-dried dispersions), syrups, and emulsions; sublingually; bucally; parenterally, such as by subcutaneous, intravenous, intramuscular, or intrasternal injection, or infusion techniques (e.g., as sterile injectable aqueous or non-aqueous solutions or suspensions); nasally, including administration to the nasal membranes, such as by inhalation spray; topically, such as in the form of a cream or ointment; or rectally such as in the form of suppositories. They can be administered alone, but generally will be administered with a pharmaceutical carrier selected on the basis of the chosen route of administration and standard pharmaceutical practice.

The term “pharmaceutical composition” means a composition comprising a compound of the invention in combination with at least one additional pharmaceutically acceptable carrier. A “pharmaceutically acceptable carrier” refers to media generally accepted in the art for the delivery of biologically active agents to animals, in particular, mammals, including, i.e., adjuvant, excipient or vehicle, such as diluents, preserving agents, fillers, flow regulating agents, disintegrating agents, wetting agents, emulsifying agents, suspending agents, sweetening agents, flavoring agents, perfuming agents, antibacterial agents, antifungal agents, lubricating agents and dispensing agents, depending on the nature of the mode of administration and dosage forms.

Pharmaceutically acceptable carriers are formulated according to a number of factors well within the purview of those of ordinary skill in the art. These include, without limitation: the type and nature of the active agent being formulated; the subject to which the agent-containing composition is to be administered; the intended route of administration of the composition; and the therapeutic indication being targeted. Pharmaceutically acceptable carriers include both aqueous and non-aqueous liquid media, as well as a variety of solid and semi-solid dosage forms. Such carriers can include a number of different ingredients and additives in addition to the active agent, such additional ingredients being included in the formulation for a variety of reasons, e.g., stabilization of the active agent, binders, etc., well known to those of ordinary skill in the art. Descriptions of suitable pharmaceutically acceptable carriers, and factors involved in their selection, are found in a variety of readily available sources such as, for example, Allen, L. V. Jr. et al. Remington: The Science and Practice of Pharmacy (2 Volumes), 22nd Edition (2012), Pharmaceutical Press.

The dosage regimen for the compounds of the present invention will, of course, vary depending upon known factors, such as the pharmacodynamic characteristics of the particular agent and its mode and route of administration; the species, age, sex, health, medical condition, and weight of the recipient; the nature and extent of the symptoms; the kind of concurrent treatment; the frequency of treatment; the route of administration, the renal and hepatic function of the patient, and the effect desired.

By way of general guidance, the daily oral dosage of each active ingredient, when used for the indicated effects, will range between about 0.001 to about 5000 mg per day, preferably between about 0.01 to about 1000 mg per day, and most preferably between about 0.1 to about 250 mg per day. Intravenously, the most preferred doses will range from about 0.01 to about 10 mg/kg/minute during a constant rate infusion. Compounds of this invention may be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three, or four times daily.

The compounds are typically administered in admixture with suitable pharmaceutical diluents, excipients, or carriers (collectively referred to herein as pharmaceutical carriers) suitably selected with respect to the intended form of administration, e.g., oral tablets, capsules, elixirs, and syrups, and consistent with conventional pharmaceutical practices.

Dosage forms (pharmaceutical compositions) suitable for administration may contain from about 1 milligram to about 2000 milligrams of active ingredient per dosage unit. In these pharmaceutical compositions the active ingredient will ordinarily be present in an amount of about 0.1-95% by weight based on the total weight of the composition.

A typical capsule for oral administration contains at least one of the compounds of the present invention (250 mg), lactose (75 mg), and magnesium stearate (15 mg). The mixture is passed through a 60 mesh sieve and packed into a No. 1 gelatin capsule.

A typical injectable preparation is produced by aseptically placing at least one of the compounds of the present invention (250 mg) into a vial, aseptically freeze-drying and sealing. For use, the contents of the vial are mixed with 2 mL of physiological saline, to produce an injectable preparation.

The above other therapeutic agents, when employed in combination with the compounds of the present invention may be used, for example, in those amounts indicated in the Physicians' Desk Reference, as in the patents set out above, or as otherwise determined by one of ordinary skill in the art.

Particularly when provided as a single dosage unit, the potential exists for a chemical interaction between the combined active ingredients. For this reason, when the compound of the present invention and a second therapeutic agent are combined in a single dosage unit they are formulated such that although the active ingredients are combined in a single dosage unit, the physical contact between the active ingredients is minimized (that is, reduced). For example, one active ingredient may be enteric coated. By enteric coating one of the active ingredients, it is possible not only to minimize the contact between the combined active ingredients, but also, it is possible to control the release of one of these components in the gastrointestinal tract such that one of these components is not released in the stomach but rather is released in the intestines. One of the active ingredients may also be coated with a material that affects a sustained-release throughout the gastrointestinal tract and also serves to minimize physical contact between the combined active ingredients. Furthermore, the sustained-released component can be additionally enteric coated such that the release of this component occurs only in the intestine. Still another approach would involve the formulation of a combination product in which the one component is coated with a sustained and/or enteric release polymer, and the other component is also coated with a polymer such as a low viscosity grade of hydroxypropyl methylcellulose (HPMC) or other appropriate materials as known in the art, in order to further separate the active components. The polymer coating serves to form an additional barrier to interaction with the other component.

These as well as other ways of minimizing contact between the components of combination products of the present invention, whether administered in a single dosage form or administered in separate forms but at the same time by the same manner, will be readily apparent to those skilled in the art, once armed with the present disclosure.

The compounds of the present invention can be administered alone or in combination with one or more additional therapeutic agents. By “administered in combination” or “combination therapy” it is meant that the compound of the present invention and one or more additional therapeutic agents are administered concurrently to the mammal being treated. When administered in combination, each component may be administered at the same time or sequentially in any order at different points in time. Thus, each component may be administered separately but sufficiently closely in time so as to provide the desired therapeutic effect.

The compounds of the present invention are also useful as standard or reference compounds, for example as a quality standard or control, in tests or assays involving the MGAT2 enzyme. Such compounds may be provided in a commercial kit, for example, for use in pharmaceutical research involving MGAT2 or anti-diabetic activity. For example, a compound of the present invention could be used as a reference in an assay to compare its known activity to a compound with an unknown activity. This would ensure the experimentor that the assay was being performed properly and provide a basis for comparison, especially if the test compound was a derivative of the reference compound. When developing new assays or protocols, compounds according to the present invention could be used to test their effectiveness.

The compounds of the present invention may also be used in diagnostic assays involving MGAT2.
